You asked this question on a mailing list. Some mailing lists don't alter envelope-from, so you'd not receive your own messages back from such mailing lists.
The implementation of mailing lists by transparent forwarding (e.g. what you'd get from a single traditional multi-address alias) has always been a problematic mode of operating a mailing list that serves users in multiple domains and in the modern world of SPF, DMARC, and widespread forgery it is unworkable in that it makes the overwhelming majority of personal mailboxes undeliverable.
What is actually dangerous for trying to block forgeries of local addresses is to look at the From: header. Modifying that is still not a dominant behavior of mailing lists and may never be, as it interferes with behavior people don't want to end.
